This next sonification was designed to have a "rainfall" metaphor to provide more context for interpreting the meaning of the sounds. An iconic sequence of rainfall-like sounds was created using the Sonification Sandbox which is a tool that maps spreadsheet columns of data into General MIDI channels. Since there is no rainfall in the General MIDI palette the noise-like Applause channel was chosen as an iconically similar sound. The pitch mapping is inverted so that light rain sounds high and soft, and heavy rain sounds low and loud.
